Abstract
Description
TECHNICAL FIELD
[0001] The application relates to the technical field of membrane separation devices, in particular to a microporous filter column and a microporous filter plate. BACKGROUND
[0002] As a highly efficient separation method, membrane separation technology plays an important role in many fields. In this technical field, microporous filter membranes stand out due to their wide range of applications and ease of operation. Microporous filter membranes are widely used in scientific research, food safety testing, chemical industry, nanotechnology, energy and environmental protection, and other fields. Their simple operation process and rapid separation effect make them an indispensable tool in scientific research and industrial production.
[0003] From a structural point of view, microporous filter membranes are very thin membrane materials with an internal structure similar to a porous sponge. The diameter of these pores is usually between 0.1 microns and 10 microns, while the thickness of the filter membrane itself varies from 0.1 microns to 1.5 microns. According to the different surface properties, microporous filter membranes can be divided into two categories: hydrophilic and hydrophobic.
[0004] Microporous filtration technology is a precise screening process specifically designed to filter out particles ranging from 0.1 microns to 10 microns. This technology relies on microporous filter membranes produced through advanced manufacturing processes, and its filtration mechanism is mainly based on surface filtration. Due to the fixed nature of the filter pore size, this technology can provide precise and reliable filtration results.
[0005] Microporous filters are precision filtration components that fix microporous filter membrane materials on a filter. Ensuring that the microporous filter membrane material can be reliably and sealingly fixed on the filter is the key to the design and manufacture of such components. Currently, common filter membrane fixing methods include adhesive fixing, hot melt fixing, and ultrasonic welding fixing. However, these fixing methods are mainly suitable for filters with relatively simple structural designs and cannot meet the fixing requirements of filter membranes in complex structures.

[0039] As shown in Figures 1 to 3 The present application provides a microporous filtration column 100, which has a first inlet 110 and a first outlet 120, the first inlet 110 and the first outlet 120 are in communication, the first outlet 120 is provided with a plurality of liquid outlets 121, the inner side of the plurality of liquid outlets 121 is provided with a microporous filter membrane 130, and the inner side of the microporous filter membrane 130 is provided with a fixed pressure ring 150. This design allows the solid-liquid mixture to flow from the first inlet 110, be filtered by the microporous filter membrane 130, and then flow out from the liquid outlet 121 of the first outlet 120, realizing solid-liquid separation.
[0040] Specifically, the first inlet 110 is the entrance of the liquid into the microporous filtration column 100, and the first inlet 110 is designed to be compatible with various containers or pipelines to facilitate the input of the liquid-solid mixture. The first outlet 120 is in communication with the first inlet 110, and the first outlet 120 is the outlet for the filtered liquid. The design of the first outlet 120 takes into account the dynamics of liquid flow to ensure that the filtered liquid can be smoothly discharged. The liquid outlet 121 is located at the first outlet 120 and is the final outlet for the filtered liquid. The design of the plurality of liquid outlets 121 takes into account the flow and pressure of the liquid to ensure that the liquid can flow out uniformly during the filtration process.
[0041] The microporous filter membrane 130 is the core part of the microporous filtration column 100, and the microporous filter membrane 130 is located inside the liquid outlet 121. The pore size of the microporous filter membrane 130 is accurately controlled, which can intercept particles of a certain size while allowing the liquid to pass through. Preferably, the material and pore size of the microporous filter membrane 130 are carefully selected according to the filtration requirements to ensure the filtration effect and service life.
[0042] In some embodiments of the present application, the microporous filter membrane 130 is a single sheet that covers multiple liquid outlets 121, facilitating installation.
[0043] In some embodiments of the present application, the fixed pressure ring 150 is located on the inner side of the microporous filter membrane 130, which serves to fix the microporous filter membrane 130 in place and prevent displacement or deformation of the microporous filter membrane 130 during filtration. The design of the fixed pressure ring 150 takes into account compatibility and sealing with the microporous filter membrane 130, ensuring that during filtration, the liquid to be separated does not bypass the microporous filter membrane 130, thereby ensuring filtration efficiency. This design of the microporous filter column 100 takes into account filtration efficiency, operational convenience, and ease of maintenance, making it suitable for a variety of industrial and laboratory environments, particularly in applications requiring precise control of filtration precision and maintaining high flow rates.
[0044] The microporous filter column 100 of the present application, by providing a first inlet 110 and a first outlet 120, both ports are connected through an internal channel to ensure smooth flow of liquid from the first inlet 110 to the first outlet 120. The first outlet 120 is designed with multiple liquid outlets 121, preferably, these liquid outlets 121 are evenly distributed along the first outlet 120 to improve filtration efficiency and uniformity. Each liquid outlet 121 is equipped with a microporous filter membrane 130 on the inside, these microporous filter membranes 130 have precisely controlled pore sizes that can effectively intercept and separate solid particles in the liquid. To ensure the stability and sealing of the filter membrane, the filter membrane is equipped with a fixed pressure ring 150 on the inside, which not only fixes the position of the microporous filter membrane 130, but also enhances the structural integrity of the microporous filter column 100, avoiding the problem of position change of the microporous filter membrane 130 during filtration, causing filtration failure. This structure can adapt to the installation needs of filter microporous filter membranes 130 of different structures and materials, such as: plastic (such as: PP, PE, PC, PA, PS, ABS, PEEK, PVDF, etc. High molecular materials), glass, ceramic, corrosion-resistant metal (such as: stainless steel pipe, titanium alloy, etc.) etc. It should be noted that when applied to industrial large-scale filtration, such as filtration of enzymes, antibodies, etc., corrosion-resistant metals such as stainless steel pipes or titanium alloys are usually selected.
[0045] In some embodiments of the present application, the microporous filter column 100 further comprises a sealing ring 140, which is arranged between the microporous filter membrane 130 and the fixed compression ring 150, and abuts the microporous filter membrane 130 on one side and the fixed compression ring 150 on the other side. The sealing ring 140 ensures the sealing between the microporous filter membrane 130 and the fixed compression ring 150, preventing the filtered liquid from bypassing the microporous filter membrane 130, thereby improving the filtering efficiency and accuracy. Optionally, the sealing ring 140 is usually made of a material with good elasticity and chemical corrosion resistance, which can form a tight contact between the microporous filter membrane 130 and the fixed compression ring 150, preventing the leakage of the solid-liquid mixture bypassing the microporous filter membrane 130.
[0046] In some embodiments of the present application, the sealing ring 140 is made of an elastic sealing material. The selection of the elastic sealing material can ensure that the sealing ring 140 maintains good sealing performance under different pressures, while also facilitating installation and disassembly. Specifically, the sealing ring 140 can be made of an elastic sealing material such as silicone, fluororubber, or polyurethane, which has good elasticity and resilience and can maintain stable sealing performance when the pressure changes or the temperature fluctuates.
[0047] In some embodiments of the present application, the elastic sealing material also has excellent chemical resistance, suitable for filtering applications in various chemical environments.
[0048] In some embodiments of the present application, the liquid outlets 121 are arranged in a radial ring outside the center of the liquid outlets 121. This design can increase the filtering area of the microporous filter column 100, allowing more liquid to pass through the microporous filter column 100 at the same time, thereby improving the filtering efficiency. Specifically, the liquid outlets 121 are designed in a radial ring layout, i.e., uniformly distributed along the circumferential direction of the first outlet 120, forming multiple annularly arranged liquid outlets 121. This design helps to improve the filtering efficiency of the microporous filter column 100 and the uniformity of liquid distribution, while reducing the dead angle and clogging phenomenon during the filtering process.
[0049] In some embodiments of the present application, the first inlet 110 of the microporous filter column 100 has a boss 111 arranged extending radially outward. The design of the boss 111 can increase the stability of the first inlet 110, and also facilitate the connection of the microporous filter column 100 with other equipment. The boss 111 can tightly fit with external equipment or pipelines, ensuring the sealing of the liquid inlet process and preventing liquid leakage. In addition, the design of the boss 111 also facilitates the installation and connection of the microporous filter column 100, improving the convenience.
[0050] In some embodiments of the present application, the boss 111 is sequentially provided with a bulge portion 112 and a filter portion 160 below, the first outlet 120 is arranged at the end of the filter portion 160, the outer diameter of the bulge portion 112 is larger than that of the filter portion 160, the inside of the bulge portion 112 is provided with a first through hole 113 communicating with the first inlet 110 and the filter portion 160, the filter portion 160 is provided with a second through hole 161 communicating with the first through hole 113 and the first outlet 120, and the inner diameter of the first through hole 113 is larger than that of the second through hole 161. This structural design helps to optimize the liquid flow path, reduce flow resistance, and improve filtration efficiency. Specifically, the design of the bulge portion 112 and the filter portion 160 below the boss 111 makes the microporous filter column 100 have better structural stability and liquid distribution uniformity. The outer diameter of the bulge portion 112 is larger than that of the filter portion 160, which helps to form a larger liquid buffer zone at the first inlet 110 and reduces the possibility of liquid directly impacting the filter membrane. The design of the first through hole 113 and the second through hole 161 ensures smooth flow of liquid from the first inlet 110 to the first outlet 120, and the larger inner diameter of the first through hole 113 helps to reduce the resistance of liquid flow and improve filtration efficiency.
[0051] As shown in Figure 4 and Figure 5 The present application also provides a microporous filter plate 200, which comprises a connecting positioning plate (not shown in the figure) and the above-mentioned microporous filter column 100. The connecting positioning plate is provided with a plurality of mounting positions (not shown in the figure), and a plurality of microporous filter columns 100 are arranged one by one in the mounting positions. Integrating multiple microporous filter columns 100 on one filter plate facilitates large-scale filtration operation. Specifically, the design of the microporous filter plate 200 allows multiple microporous filter columns 100 to be integrated on one connecting positioning plate to form a modular filtration system. The connecting positioning plate provides a plurality of mounting positions, each of which is designed to have a size and shape matching the microporous filter column 100 to ensure that the microporous filter column 100 can be stably installed in place. This modular design facilitates the installation, maintenance and replacement of the filter plate, while improving the flexibility and efficiency of the filtration system.
[0052] In some embodiments of the present application, the connecting positioning plate comprises an outer frame 210, which defines a filtering space inside. A plurality of microporous filter columns 100 are arranged in the outer frame 210 in horizontal and / or vertical directions, and the connecting parts between adjacent microporous filter columns 100 have at least one reinforcing rib 230 connected to the outer frame 210 in the horizontal and / or vertical direction. The outer frame 210 of the connecting positioning plate is designed as a structural member, which not only provides a filtering space, but also enhances the structural stability of the entire filter plate through the internal reinforcing ribs 230. The microporous filter columns 100 are arranged in horizontal and vertical directions to form a grid-shaped filtering area. The design of the connecting parts and the reinforcing ribs 230 ensures the close connection between the filter columns, prevents liquid leakage, and also improves the overall strength and durability of the filter plate.
[0053] In some embodiments of the present application, the outer side of the outer frame 210 is provided with an ear 220 along the side facing the first outlet 120, and the reinforcing rib 230 is connected between the connecting part and the ear 220. The design of the ear 220 can provide additional support, fixation, and connection points, so that the microporous filter plate 200 can be more easily connected with other equipment or pipelines. The reinforcing rib 230 connects the ear 220 and the connecting part, further enhancing the structural stability of the filter plate, ensuring that the filter plate can maintain its shape and function under high pressure or high flow filtering conditions.
[0054] In some embodiments of the present application, the number of mounting sites is 24, 48, or 96. Specifically, the number of mounting sites determines the number of microporous filter columns 100 that can be installed on the filter plate, thereby affecting the processing capacity of the entire filtering system. The design of 24, 48, or 96 mounting sites provides users with different scale filtering demand choices. This design makes the filter plate adaptable to different sizes of filtering tasks, from small laboratory applications to large industrial production environments. Those skilled in the art can choose the appropriate number of filter columns according to the actual filtering requirements, improving the flexibility and adaptability of the filter plate.
[0055] The microporous filter plate 200 of the present application fixes a plurality of microporous filter columns 100 through the outer frame 210, and increases the strength of the microporous filter plate 200 through the reinforcing ribs 230 and the lugs 220, so as to realize convenient installation and combination and complete the filtering effect. Further, the microporous filter column 100 is provided with the first inlet 110 and the first outlet 120, and the two ports are connected through the internal channel to ensure that the liquid can flow smoothly from the first inlet 110 to the first outlet 120. The first outlet 120 is designed with a plurality of liquid outlets 121, which are uniformly distributed along the first outlet 120 to improve the filtering efficiency and uniformity. The inside of each liquid outlet 121 is provided with a microporous filter membrane 130, which has a precisely controlled pore size and can effectively intercept and separate solid particles in the liquid. In order to ensure the stability and sealing of the filter membrane, the inside of the filter membrane is also provided with a fixed compression ring 150, which not only fixes the position of the microporous filter membrane 130, but also enhances the structural integrity of the microporous filter column 100, so as to avoid the problem of position change of the microporous filter membrane 130 during the filtering process, causing filtering failure. The structure can adapt to the installation requirements of microporous filter membranes 130 in filters of different structures and materials, such as plastic (e.g. PP, PE, PC, PA, PS, ABS, PEEK, PVDF, etc. high molecular materials), glass, ceramic, corrosion-resistant metal (e.g. stainless steel pipe, titanium alloy, etc.), etc. It should be noted that when applied to industrial large-scale filtration, such as filtration of enzymes, antibodies, etc., corrosion-resistant metals are usually selected from materials such as stainless steel pipe or titanium alloy.
